Compositions of minerals from the Coto high-Al chromite deposit, Zambales ophiolite, Philippines

This dataset presents a series of elemental and isotopic compositions for rocks collected from the Coto high-Al chromite deposit, Zambales ophiolite, Philippines, including the major element compositions of chromite and in-situ Li isotopic compositions of olivine. These data were used to constrain parental magma compositions of the high-Al chromite ores, nature of their parental magma sources, and geodynamic setting during the chromite mineralization.
